Erwin Sattler Regulator 1920 Automatic Rose Gold Watch

The Regulator 1920 wristwatch brings delight to its owner with outstanding aesthetics, precious materials, impressive craftsmanship and functional perfection − just what you’d expect from a masterpiece by the Erwin Sattler manufacture. This is a timepiece that embodies the history of horology, incorporating examples of its distinguishing characteristics and accomplishments.

The Regulator 1920 takes its name from its two distinguishing characteristics: A movement from the 1920s and a Regulator dial in the style of the precision pendulum clocks. It boasts an impressive solid gold housing that is 49 millimetres in diameter, 90 grams in weight and water resistant up to a pressure of five bar. The timepiece’s allure lies in the multitude of details it contains. Seconds, minutes and hours are indicated by the manually domed and blued hands on the dial, which is made of solid silver. Elaborate lines and shapes give the face of the wristwatch a unique look, since every model is hand-guilloched by Jochen Benzinger, a true master of his profession.

Guillochage, a popular practice that has prevailed for many centuries, refers to the application of intertwined geometric figures on metal. As well as providing subtle expression through design, this technique also allows for immense artistic variety. 
The time-consuming yet extremely worthwhile workmanship of the timepiece does not just stop at the guillochage of the dial and movement plate, however. The sapphire crystal case back on the reverse allows the ticking microcosm to be seen in all its beauty. Here, the observer discovers an art of skeletonization that has become something of a rarity. This too has been completed by Jochen Benzinger. The craftsman requires a great deal of time and a great muse to create the fascinating recesses and the delicate shapes that emerge from them. First, he marks the outlines of the planned skeleton with a needle. After applying fine holes, he then removes the excess material using a special saw. Additional steps apply for bevelling the edges and engraving the surfaces.

Although the ES06 calibre of the Regulator 1920 runs with only 1/1,000,000,000 ps, the immutable laws of the mechanics demand rigorous attention.
Watch enthusiasts with a keen eye will immediately notice the arrangement of the winding and time-setting crown at the “6” on the anniversary wristwatch. This in part due to the 'Lépine' style of the movement. However, the unusual positioning also serves to protect the valuable cuffs and the ergonomics as well as preventing the winding shaft from bending. Experienced owners of hand-wound wristwatches take them off their wrist before tightening the mainspring, as this makes the act of winding a great pleasure − in the case of the Regulator 1920, this is also thanks to the solid gold crown in the design of the bolts on Erwin Sattler precision pendulum clocks.
The historically significant movement provides around 36 hours of running power with a fully taut mainspring. The quality features of the wristwatch also include a Rücker mechanism with a self-developed, manufactured and finished swan neck fine adjustment system, as well as a fine Breguet-style spring with a bent-up end curve and a thrice screw-fastened minute wheel jewel bearing. The external décor of the ticking masterpiece is completed by a hand-sewn alligator-skin strap and a solid gold push-button folding clasp.
